Abstract
(EN) Provided is a radiographic image generation system that makes it possible to display quickly thinned data on a screen. A radiographic image generation system (30) is provided with a radiographic image detector (1), a console (31), an offset correction value generation means (31), and a radiation generation device (34). The console (31) displays on a display unit at least one of the following images: the image that is formed in accordance with thinned data based on thinned data (f(x, y)) or real imaging data (F(x, y)), the image that is formed after the image-processing of thinned data in accordance with such thinned data or real imaging data that gain correction processing and offset correction processing based on an offset correction value are carried out in accordance with the thinned data or real imaging data for the forming thinned data, and the image that is formed after image processing in which gain correction processing and offset correction processing based on an offset correction value is carried out for the real imaging data.
(FR) La présente invention concerne un système de production d'image radiographique permettant d'afficher rapidement des données amincies sur un écran. Ledit système de production d'image radiographique (30) est pourvu d'un détecteur d'image radiographique (1), d'une console (31), d'un moyen de production de valeur de correction de décalage (31), et d'un dispositif de production de rayonnement (34). La console (31) affiche, sur une unité d'affichage, au moins l'une des images suivantes : l'image qui est formée conformément aux données amincies sur la base de données amincies (f(x, y)) ou de données d'imagerie réelle (F(x, y)) ; l'image qui est formée après le traitement d'image des données amincies conformément à de telles données amincies ou des données d'imagerie réelle, le traitement de correction de gain et le traitement de correction de décalage sur la base d'une valeur de correction de décalage étant réalisés conformément aux données amincies ou aux données d'imagerie réelle pour la formation de données amincies ; et l'image qui est formée après le traitement d'image lors duquel le traitement de correction de gain et le traitement de correction de décalage sur la base d'une valeur de correction de décalage sont réalisés pour les données d'imageries réelles.
